HAND FIRE-EXTINGUISHER.

SEPECIFICATION forming part of Letters Patent No. 320,225, dated June16, 1885.

Application filed January 28, 1885.

To all whom it may concern.-

Be it known that I, OLIVER E. CONNER, of Hartwell, in the county ofHamilton and State of Ohio, have invented a new and useful Improvementin Hand Fire-Extinguishers, which improvement is fully set forth in thefollowing specification and accompanying drawings, in which Figure 1 isa longitudinal sectional view of my hand fireextinguisher. Fig. 2 is aview of the same closed; Fig; 3, an enlarged longitudinal sectionshowing the construction of the plunger within and of the cap andejecting-tube at one end, and Fig. 4 rear end of tube.

My invention relates to hand or portable fire-extinguishers adapted toreceive any suitable fluid compound which on being ejected on a firewill extinguish the same; and the nature of my invention consists in anovel device for the purpose above named, which will be fully understoodfrom the following dcscription, when taken in connection with theannexed drawings.

In the accompanying drawings, A represents a tube of any suitable sizediametrically, and as long as may be convenient, having at one end ahead, 13. Centrally in this head is placed a small nozzle, 0, whichprojects outwardly from the head, as shown more fully in Fig. 3. Aroundthis nozzle 0, and attached to the end of the tube A. is a conical cap,D, having a screwthreaded end, E, over which is placed a screw-threadedcap, F. On the inside of the screw-threaded cap F, I place a cushion, G,of felt, cork, or gutta-percha, so that when the cap F is screwed downthe cushion binds against the end of the nozzle 0, thereby retaining theliquid within the tube A, and also preventing the air from entering andimpairing the efiiciency of the liquid.

H is a rod or bar having at its rear end a handle, I, so that it can bereadily grasped by the operator. This rod projects centrally through thehead J at the rear end of the tube A.

The forward end of the rod H within the tube A is provided with a cone,K, the apex of which is soldered to the rod H. This cone is providedwith a number of perforations, and is provided at its base with aconcave or (No model.)

dish-shaped plate, M. Centrally it is provided with an opening, IT. Inthis opening a ball-valve, O, rests, and a cage, P, is suitably securedto the dish-shaped plate M directly over the ball-valve, so as to keepit in position and assure its return to the seat formed by the apertureor opening N. It is obvious that as the base of the cone covers theentire area of the tube A,if the tube is filled with liquid and theplunger is drawn rearwardl y, the liquid will be forced through theapertures L, and thence through the open ing N, raising the valve 0 fromits seat, escaping thence into the opposite side of the plunger-head,and that when the plunger is moved forward the Valve will be drawn backinto its cage 1 and the liquid ejected through the nozzle O with a forceproportionate to the motion of the plunger. Preparatory to placing theliquid in the tube, the cap F is screwed down and the plunger placedwithin the tube in the position indicated in Fig. 1. The tube A isfilled with the proper liquid through the head J, which is then solderedin place, and the rod H is soldered to this head, as shown at Q, Fig. 1.

\V hen it is desired for use, the cap F is first removed and the tubegrasped by one hand and the plungerhandle in the other, and by atorsional movement of the rod the solder Q is loosened, and the plungeris in position to be reciprocated and the liquid ejected, as heretoforestated.

Instead of soldering the rear end, and to enable me to refill the tube,and. also obviate the necessity of resoldering the rod, H to the head J,I provide the rear head, J, preferably conically shaped, as shown inFig. 4, with a screw-thread, upon which is fitted a screwthreaded cap,It. The rod H passes centrally through this cap, and is soldered to thesaid cap It, as shown at S. Instead, therefore, of merely releasing therod from the soldered head, as shown in Fig. 1, by means of rupturingthe solder, the rod is unscrewed from the head J, as shown by T. The rodH is then in position to be moved forward and backward in the process ofejectingthe liquid.

In practice I shall employ a suitable packing or closing device, U,which will prevent the liquid from being casually forced out of the tubebackward when cap R is removed. This packing or closing device may beomitted. Having described my inventin,\vhat I claim 1s 7 1. In afireextinguisher, the combination of the tube A, having at one end thehead B, provided with the projecting nozzle 0, the cap D, provided witha serew-cap, F, the plunger H within the tube A, having a coni- 10cal-shaped head provided with the depressed valve-seat M, the valve 0,cage 1, and the head Q, soldered to the rod H, as and for the purposesubstantially as herein set forth.

2. In a fire-extinguisher, the tube or liquidreceptacle A, the nozzle 0,fixed cap D, re-

movable sealing-cap F, and a head, J, in combination with a perforatedplunger, a valve, anda rod therefor, substantially as described.

3. The combination, with a fluid-receptacle provided with a nozzle and aclosing-cap 2o therefor, a rear head, J, provided with a screw-cap, anda plunger-rod soldered to this cap, substantially as described.

In testimony that I claim the foregoing I, have hereunto set my hand,this 16th day of January, 1885, in the presence of Witnesses.
